Bought a new Trek 7.5 FX back in March. Had some minor problems that adjusted out and some that have not. Put 800 miles on the bike in nine weeks and both tires now have blisters on them. Nice weather and my riding is 0 right now because the bike store is in another town. The bike store will honor the warranty on the (Bontrager) tires I think but is this what to expect? Constant adjusting and tires wearing out every two months. Rode an old Specialized mountain bike 2500 miles and only put a tube in a tire the year before deciding to invest in a really nice bike that seems to be high maintenance at best. Beginning to wonder if I should have gone to Walmart. Should I consider getting rid of this bike and move to another brand or am I just expecting too much out of the product? I would think not for what it cost.
